Why not post this from your main account? are you too afraid of the backlash you will receive?
I don't think any flags are necessary for any. Just assume that everyone here is a lair, cheater, and stealer and take the proper pro-cations when trading, and mind your own business
Even if your first assertion is possibly true. Not that we are an alt of anyone. That is merely a poor reflection on this state of the trust system. Why should one asking such questions be at risk of getting negative trust. So unless you have video evidence of another member posting on this account why bother considering it? what relevance does it have to the initial post. The answers should be the same if any of those questions was asked by ANY other member.
Allowing whistle blowers to be given scam tags is the very reason a sensible person may decide to use a shield here. Stop the abuse and REALLY blacklist abusers and no need for shields.
Please tell theymos to delete the entire trust system them and just put a message on every ones account " this person is possibly going to scam you as soon as they can"
